Little bit about brushes in general. Tom Ford brushes are made from natural goat hair. Personally I prefer natural hair to synthetic hair, even though the new generation of synthetic hair are just a soft as natural hair and doesn’t shed as much as natural hair. I find natural hair, may be due to natural irregularity in each strand are better at picking up colour and better at applying colour in softer layers. The only time I prefer synthetic hair over natural hair is for cream products.
